The problem in that case was, according to Google, a bug in the software that distributed load between its different data centers. The Gmail outage only resulted in people not having access to their email for a few hours. No one got killed. Nothing exploded. It was an inconvenience, and while it was a significant inconvenience for some of Gmail’s users, it was still just that: an inconvenience. This article is about some of the more dire consequences of software errors through the years. Incidents that make the Gmail outage seem rather trivial. 2009-04-05T19:11:18Z kasi77 software, load, email, gmail, it, bug

The obvious benefit is that they can help websites to give end users a speedier web surfing experience, but there is also another very positive side effect for the entire Internet, and it will become more noticeable the more common CDNs become. The positive side effect is this: More CDN usage means less load on the Internet backbone. 2009-01-13T13:31:45Z kasi77 web, internet, load

A quelques exceptions près (comme par exemple un site de partage de vidéos), il n’est peut-être pas en effet très judicieux de perdre du temps sur cet aspect très technique sans savoir si le succès sera au rendez-vous : on parle alors d’optimisation prématurée. 2008-03-12T19:07:06Z kasi77 load, flickr, montée en charge, slides, web

]]> Comment ça marche : la haute disponibilité web - Web Interdit http://www.webinterdit.com/content/index.php/2006/01/19/34-comment-ca-marche-la-haute-disponiblite-web Pour gérer des milliers ou des millions d'utilisateurs, un site web se doit de mettre en place un certain nombre de technologies afin que les visites des utilisateurs soient garanties et agréables. En termes techniques, on parle de redondance et de répartition de charge (load balancing en anglais). L'association de ces deux paramètres permet d'atteindre ce qu'on appelle la haute disponibilité : en gros un service qui ne peut pas tomber en panne et qui peut facilement monter en charge. 2006-11-11T09:14:14Z kasi77 web, site, vulgarisation, haute dispo, load
